You'd be surprised how little weight hard work carries relative to positive attitude coupled with an acceptable amount of work (former manager here). Performance reviews aren't usually that objective. If you're getting dinged, it might be a problem with your attitude vs your performance. It's unfair, but you're working with humans, not vulcans. Said another way: If management likes you personally, and you work hard enough, you're not going to get bad performance reviews. If this coworker is a ball hog, that's a different story, and management will pick up on it over time. The best thing you can do in the meantime is worry about your own output and do good work with people who do want to work with you.
